ABSTRACT
Carica papaya is made to develop pharmacognostical characters of leaf with their morphological, microscopical, and physical characters including histochemical analysis. Morphological evaluation as color, odor, taste, size, shape, surface, and powder microscopy of plant shows the presence of endosperm cell which is polygonal in shape and contains aleurone grains and oil droplet, cell of testa, yellow coloring matter, and starch grains. Quantitative leaf microscopy to determine palisade ratio, stomata index, and vein-islet number is carried out. Peels are removed mechanically through epidermal peeling off and stomatal index (SI) is calculated. The vein-islet number, vein termination number, and palisade ratio of lamina are determined according to the standard method. We prepared the extracts of plant with different solvents for determining the different extractive values by maceration, Soxhlet extraction, successive extraction process, and determination of ash values, pH value, moisture content, and phytochemical screening to show the presence of carbohydrates, phenolic compounds, flavonoids, alkaloids, proteins, saponins, and lipids in the drug extract and fluorescence analysis in different solvent. Analysis of pesticide residues, aflatoxin, and heavy metals are also performed
ABSTRACT
In present study plant of Arjuna has been taken for physical and chemical analysis in terms of microtome of bark, powder study, loss on drying, ash values, extractive values, bulk density, Acid insoluble ash, Water-soluble Ash, Water-soluble extractive value, Alcohol-soluble extractive, pH range, TLC, Tapped density, Compressibility index, Hauser ratio, Angle of repose, Ultra violet fluorescence analysis of drug, etc. Physical and chemical analysis an important place in standardization of Ayurvedic drugs in order to make its global acceptability. The plant of Arjuna botanically named as Terminalia arjuna linn.; family Combretaceae, has traditionally been used to treat many diseases especially heart disease for centuries, that’s why it is called as “Guardian of the heartâ€. Transverse sections of Arjuna bark shows the calcium oxalate crystal, starch grains and lignified cells respectively shows that Xylem Vessels, Sclerenchymatous Fibers, Cork Cells, Tracheids, Sclereids, LOD value of the sample of Arjuna is 5.63%. According to result the Arjuna has three Rf vaule0.70, 0.42, 0.28 table1.4. Angle of repose of powder sample shows the flow of powder. The extractive value of Arjuna have different solvent like water, ethanol, isopropanol, acetone, chloroform, benzene, toluene, petroleum ether, hexsene are respectively 50.80, 41.07,30.37, 8.95, 0.96, 0.67, 0.52, 0.51, 0.46.
ABSTRACT
Objective of the present study was to carry out the physicochemical and phytochemicals standardization of Lepidium sativum Lseeds to establish the standard pharmacognostical parameters of this valuable medicinal plant. Many standardization parameters of Lepidium sativum were analyzed. Standard method was adopted for the preliminary phytochemicals screening. Analysis of pesticides residues, aflatoxin & heavy metals were also performed. The sections of seeds were prepared for quantitative microscopic parameters. The air dried powdered plant material was subjected for determination of physicochemical standardizations like ash value, Extractive value and fluorescence nature of the powder drug using light of short and longwavelength of 254nm and 366nm respectively. Phytochemical screening was performed for the identification of phytoconstituents in the plant which was helpful in the development of analytical profile. The morphological and microscopic examinations of drug were revealed the presence of endosperm cell which are polygonal in shape and contain alerone grains and oil droplet, cell of testa, yellow colouring matter and starch grains. Preliminary phytochemical screening showed the presence of carbohydrates, phenolic compounds, flavonoids, alkaloids, proteins, saponins and lipids in the drug extract and flourescence nature of drug was confirmed by fluorescence analysis in different solvent. Concentrations of heavy metals,ash value and extractive value were determined and found within acceptable Pharmacopoeial limits. Pesticides residues and aflatoxins were also determined but not detected in the tested samples. The physicochemical and phytochemical standards which are outcome of this research may be utilized as substantial data for identification and standardization of L. sativum seed.
